The girl who was just beginning to fall in love couldn't hide the joy on her brows, Tang Ning was scared, she had to think of a way to hide it, looked around, and saw a ball hanging on the wall, so she said to Linfield: "You take that one off and give it to you." ”

Linfield wondered what this ball was, and when he took it down, he untied the tether and was pleasantly surprised to find that it was actually a straw hat. The magical straw hat was rolled into a ball, and it was completely unseen to be rolled and pressed after unfolding, and it was light and dense, which seemed to be a very high-end product.

Lin Fei smiled like a summer flower: "Thank you, Master!" What's the name of this hat? It has been rolled up without any creases. ”

Downing: "The Japanese who went on an expedition to Granada gave me a local specialty, called a Panama hat." The sun is so hot that the workers have to wear straw hats, which are said to be woven for six months by the finest craftsmen, using the finest grass. I guess the secret to the straw hat's super flexibility lies in this grass strip. ”

Linfield pinched the straw hat as if he had a new toy, and praised: "It's really good, I picked out a lot of hats a while ago, so I've seen all kinds of high-end hats, and there are no good ones like this, hey, you ask that Japanese to get more ones, I can open a straw hat shop." This one is worn by men, but I want it too. She said and put it on top of her head, like an aura cowgirl.

Downing couldn't help this lively cowgirl and asked, "Do you want to be a football referee?" Or do you want to do a PhD? Or do you want to act in a drama? Or be a straw hat shop proprietor? Is there a quasi-spectrum? ”

The cunning in Lin Fei's eyes began to bloom again: "The quasi-spectrum is - I want to be an all-knowing and all-powerful gangster!" Like Master! Aren't you also messing around? Now that they are all mixed into the emperor, they are really my idols, and I must at least be the queen of a small country, right? ”

Tang Ning was stunned: "I'm a gangster? Your summary of me is so good, it's really my ......"

Linfield: "Confidante! Right? Chattered! I already have a hunch that you're going to be the king of America, haha, that should be your ultimate goal. ”

Downing almost burst out laughing: "Americans don't need kings, they have a tradition of self-government." ”

Lin Fei said seriously: "When the time comes, they can't help it." You led the southerners to defeat the Yankees and let the Yankees pay $10 billion in compensation, but they would definitely not be able to afford it, so they had to ask you to be the king, and as soon as you became the king and gave amnesty to the world, you exempted the Yankees from $10 billion in foreign debts. The Americans are not only willing to make you king, but they are also very happy. ”

Tang Ning laughed and shook his head: "You look like a gangster than me, what a master is a master!" ”

The more Linfil spoke, the more true he became, and said, "When the time comes, you can give me California, and I can be the queen of California, so happy!" She clasped her hands on her chest again, looking forward to the glorious political career of the queen, and her beautiful little face looked ridiculously funny.

Downing: "Huh? You've got your eye on California...... Why? ”

Linfield: "Uh...... Because, of course, it's the closest to China, how? It seems like you have a different view of California too? ”

Downing smiled: "If there is such a day, California can't be disposed of casually, it has the West Coast, of course, it is a military strategic location." ”

Linfield thought that he had guessed the mind of a certain Tang, and while proud, he continued: "If you conquer the Southerners, it will be a trouble......

Tang Ning leaned back and sat on the sofa, waiting for the little girl's little brain.

Linfield's pointed fingers snapped his fingers without ringing, and he said, "There you have it!" Isn't there a lot of controversy over the ownership of territories between the north and the south? Nevada, Utah, Colorado, New Mexico, you send troops to take them all. When the southern Yankees are angry, you will declare war again, and you can do a big job, and domination of the rivers and lakes is just around the corner. ”

Downing smiled but said nothing.

After a long time, the little girl couldn't wait for Master's response, and asked, "Did I guess it?" ”

Tang Ning continued to laugh without saying a word, and the little female disciple lost her patience and hugged her master's arm and shook it to strengthen her questioning. When the doorbell rang, Linfield jumped up from the master's side to open the door, and a thin middle-aged man stood in the doorway, it was none other than Tyndall, a professor at the Royal Institute of Science who had an appointment with Downing.

Linfield exclaimed, "Hello, Professor Tyndale! "Very polite.

Tyndale: "Oh, little girl, hello, the hat is so pretty! ”

Lin Fei smiled sweetly: "Thank you!" Please come in! ”

I really didn't treat myself as an outsider, and Tang Ning was embarrassed to drive her away, so he had to introduce: "This is Miss Faraday, my doctoral student, since she is here, let her listen to it too, what is the professor talking to me about?" ”

Tyndale: "I found something very interesting, look! Only then did Downing notice that he was holding a box.

As soon as this thing showed its face, Tang Ning blurted out: "The phone ......"

Tyndale: "What? This is an 'electric sound transmission device', sent by an Italian, he is so poor, even the postage is paid by me, and I promised to help him apply for a patent, he doesn't have the money. ”

Tang Ning smiled, this is indeed the original invention of the telephone, the inventor is the Italian Muzzi, as a lover of the history of science and technology, if the inventor of the telephone does not know, it is considered blind. In real history, this hapless poor inventor was robbed of his patent by Bell of Canada because he couldn't pay the patent fees, so much so that he thought that many people thought that Bell was the inventor of the telephone.

Of course, Tyndale didn't know that Downing saw through the usefulness of the "electrical sound transmission device" at a glance, and he took the trouble to explain how to play with it. The little girl excitedly dragged the cable to another room, and closed the door to isolate the sound transmission between the two places, so as to show the power of the "electric sound transmission device".

Downing casually discussed with the little girl in the original telephone what should be written in those hundred brief histories of the world, and Linfield said, "Whatever, anything." Tang Ning: "In this case, how about I write 'The Trial of the East King' is a good drama'?" ”

Linfield grinned grimly.

Tyndale watched Downing joking with his female PhD student, and a strange feeling welled up in his heart, as if the two of them didn't seem very surprised by such a magical device.

Downing called Linfield back and said to Tindale: "This thing is good, it is rare for you to find it in Italy, what is the name of the inventor?" ”

As soon as Tyndale said it, it was the main one: Antonio Muzi.

Telephones are certainly a very lucrative business, and in real history, before AT&T was partitioned, IBM was the second largest company in the United States. After AT&T was divided into seven companies, IBM's ranking became eighth. Tang Ning himself does not like to make phone calls, but likes to send telegrams, but since the opportunities to make a lot of money have come to his door, it is impossible for him to refuse.

Great inventions can enhance national cohesion, who said that the Italians can't do it, the epoch-making thing of the Nima telephone is an invention of the Italians! Isn't it glorious for our emperor to do? Downing had instantly decided to drag the London fibre team to Italy to work with Muzzi to improve the telephone. The first is the invention of the voice telegraph, and then the immediacy of the voice telegraph is improved, and then it becomes a two-way telephone, and it becomes a real telephone.

Since becoming the emperor of Italy, he has really drifted away from the British Empire, and Tyndale said that he was helpless. In order to comfort Tyndall's fibre team, Downing said that the result this time will be declared an Italian-British cooperation. From a technical point of view, this is indeed a British-Italian cooperation, because in Downing's mind, a three-way cooperation pattern has been planned for the telephone company, one is Muzzi's team, one is Tyndall's team, and the other is Faraday Power's team.

Do telephone cables still need to be dug from scratch and deployed? No, directly transform the power line to enable it to transmit telephone information, which can avoid a huge waste of resources, and also make the telephone company have a large network at the beginning, and where there is a power grid, there is a telephone network, even if someone invents the telephone at the same time, he will find that it is impossible to compete with Downing's telephone company, because the other party's network has already been like a heaven and earth network.

However, this is only a network in the community, and the communication trunk still relies on optical fiber, because the speed of electrical signal transmission is not fast enough, and only the speed of light can bear the requirements of intercity and even international telephone communication.

It's time to reveal a mystery, and Tang Ning gives the little girl an order: "Call all my students, and let them all open their eyes as a teacher today." ”

The little junior sister received an order to drive her father's ironclad evidence of his bottomless pampering of his daughter: an expensive Continental GT, one by one to summon the senior brothers, the first handsome brother who was summoned thought that the little junior sister was interesting to him, and he was very excited, but unfortunately after he got in the car, the little junior sister went to summon n n senior brothers, including the senior brother Maxwell, a car of 6 people was crowded, full of going to the mentor's house to witness the moment of miracle.

The last time he revealed the magical microcosm of subatoms, he published in the journal Nature that he obtained electrons by discharging electricity from a glass vacuum tube, and now Downing wants to reveal the mystery of a new mysterious phenomenon that produces electric current by irradiating metal with ultraviolet light, that is, the photoelectric effect. Because this will be the core technology of the telephone company, otherwise how to use optical fiber to transmit telecommunication signals. To put it simply, telephone technology is a technology that converts sound waves, telecommunications, and optical signals into a cycle. This is, of course, much more sophisticated and complex than the telephone technology used by Muzi or Bell.

He even wants to look for masters in discrete mathematics in the consortium system of the Global University of Technology, and further develop digital sampling of analog signals of sound, so as to facilitate sound processing, denoising, compression, sharpening, etc., and do basic research for the future of speech technology.

It is an astonishing fact that light can generate electricity, and it makes the brains of high-achieving students also generate electricity and short-circuit it for a short time, and suddenly immerse themselves in a completely unfamiliar magical world. (http：/／.）。

Tang Ning introduced "his own research results": "You should pay attention to the fact that only ultraviolet rays can currently produce current, and it is also related to frequency, the frequency is lower than a certain threshold, no matter how large the time and intensity of the light will not produce a trace of current, this is the key point for everyone to think about, why is this so?" ”

"If you can think of a reasonable possible theory, you can get a Ph.D., come on!" Tangning said with a smile. This is by no means something that can be thought of overnight, because the first plausible theory in real history came from Albert Einstein, for which he was awarded the Nobel Prize.

In the face of Yan Sù's academic research, the little junior sister didn't dare to make a mistake, so she raised her hand first. Downing motioned for her to speak, and she said, "Have you already thought of a reasonable explanation?" ”

Downing: "No, but I've been discovering this phenomenon for a long time, and it can be called the photoelectric effect." Come on, everyone. ”

Unexpectedly, light could be converted into telecommunications in this way, and Tyndale fell into an excited myth.
